karpathy-graph-query SKILL.md skillA
karpathy-graph-query from andersonlimahw/lemon-ai-hub is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add andersonlimahw/lemon-ai-hub/karpathy-graph-query@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Stage 4 of the karpathy-graph pipeline. Answer multi-hop questions from a knowledge graph by retrieving a bounded subgraph with edge citations, and ground or refute claims against actual graph paths. Use when the user asks a question that spans several facts, asks how two things connect, asks to verify or ground a claim, or when an agent needs task-specific context from an existing graph.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Query
The graph exists so agents stop replaying transcripts. That only works if
retrieval stays **bounded**.
## The rule
**Never dump the graph into a prompt.**
Not `graph.json`, not the full node list, not "just this once because it's
small". Retrieve the connected state needed for the current decision, and
nothing else. A graph used as a context dump is worse than no graph — it costs
the same tokens plus the build.
## Retrieval procedure
1. Resolve the entities the question mentions
2. Expand one or two hops over the edge types that matter
3. Filter by type, source, or date when the question implies it
4. Serialize within a token budget
5. Keep the edge ids so the answer can cite them
```bash
KG="${CLAUDE_PLUGIN_ROOT:-plugins/karpathy-graph}/scripts/kgraph.py"
python3 "$KG" --name "<graph>" query "vendor X" \
--hops 2 \
--edge-type SUPPORTS --edge-type MENTIONS \
--max-nodes 40 \
--format context
```
## Choosing hops
| Hops | Use for |
|---|---|
| 1 | "what is directly attached to X" |
| 2 | most questions — the default |
| 3 | explicit multi-hop chains (X → Y → Z) |
| 4+ | almost never; you are retrieving the whole graph with extra steps |

How to install
mdr add andersonlimahw/lemon-ai-hub/karpathy-graph-query@sha256:a06c8fea87ea42fcThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
